Method Detail

public int getMasterNodeId()

getTransactionId

public long getTransactionId()

the transaction id embedded within this loggable object. Objects that have no transaction id should return 0.

public long getDTVLSN()

setDTVLSN

public void setDTVLSN(long dtvlsn)

hasLoggedEntries

public boolean hasLoggedEntries()

Returns true if there are changes that have been logged for this entry. It's unusual for such a record to not have associated changes, since such commit/abort entries are typically optimized away. When present they typically represent records used to persist uptodate DTVLSN information as part of the entry.
